I am interested in using aluminum tubing for building a tubular chassis but most people say that aluminum does fatigue crack. But I was thinking that it has been done and aluminum can be used for a car chassis.
Audi uses aluminum for their monocoque chassis....
Is there anything I should know about this Audi chassis?
Isn't fatigue cracks also a problem with this Audi chassis since it's also made of aluminum....or perhaps also with the Acura NSX?
